F To all whom it may cancers:

Be it known that I, JOSUA H. SCHMIDT, a citizen of the United States, residing at Yonkers, in the county of Westchester and State of New York, have invented new and useful Improvements in Slicing-Machines, of Which the following is a specification.

This invention relates to slicing machines and while it will hereinafter be described as a bread slicing machine, it will be apparent as the description proceeds that the machine,

is equally well adapted for slicing any material in the form of a loaf or bar such, for example, as Bologna sausage, ham, tongue, etc.

The object of the present invention is to produce a slicing, machine of the character referred to which is operated automatically provide feeding mechanism of such a charactor that the step by step movement of the feeder head hereinafter described will be arrested in time to prevent the feeder head ter.

With the above and other objects in view,

I erally extending'handle or grip 17 to enable from coming in contact with the slicing cutthe invention consists-in the novel construction', combination and arrangement of parts,

as herein described, illustrated and claimed. In the accompanying drawings :Figure 1 is a front elevation partly in section of a slicing machine embodying the present invention. Fig. 2 is a plan view of the same. Fig. 3 is an end elevation partly in section of the machine, showing the slicing cutter in elevation. Fig. 4 is an elevation of the 0p posite end of the machine omitting the adj acent wheel and showing the rotary shaft in cross section. Fig. 5 is an enlarged vertical cross section on the line 55 of Fig. 1. a Fig. 6 is a detail vertical'longitudinal section on the line 6-6 ofFig. 5 enlarged.

The slicing machine contemplated connected by a trough comprising the hot in this invention 'COIIIPIISGS a frame which is made tom wall 1, front wall 2 and rear wall 3, the front Wall 2 being of less height than the rear wall 3 to-admit of the back and forth movement of the feeder head which is deslgnated generally at C. 1

Connected to the top and outside of the frontwall 2 is an anglebar 4 forming a Specification of Letters Patent. Patented Aug; 24,1915,

supporting guide for the feeder head C, a

retaining lip 5 on the feeder head engaging beneath the supporting guide 4 and serving to prevent the feeder head from becoming disengaged orgetting out of place.--- The. feeder head comprises a fixed gripping jaw 6 and a movable gripping jaw 7 both of said jaws being provided with teeth orv spurs 8 extending toward: each otherso as to grip the bread or other bbject' between them.

The movable jaw 7 is mounted upon a vertically slidable runner 9 which is adapted to be slid upwardly and downwardly on a vertical guide post 10 extending upwardly from the body of the lower stationary jaw 6 as shown imFig. The runner 9 is provided with a wing or extension 11 carrying a headed pin or stud 12 which is received in a longitudinal slot 13 in a hand operable lever. 14 which is fulcrumed at 15 on th'e upwardly extending arm 16 of the feeder head C, all v as shown in said Fig. 5. The'operator by grasping the handleof the lever 14 may.

move the slidable jaw upwardly and downwardly so as to admit and grip the'loaf of bread or other object preparatory to start- J ing the machine in its slicing operation.

The feeder head C is provided with a lat the feeder head to be moved back to its po [sition to receive a new loaf of bread. This handle 17 is enlarged as shown at 18 and spring pressed latch 24 provided with a tooth 25 adapted to engage the teeth of the rack bar 23 as clearly indicated in Fig. 6. The latch 24 has associated therewith a latch operating" and releasing lever 26 best illustrated in Fig. 6, said leverv being pivotally mounted at 27 on the handle or grip 17, a spring 28 being interposed between the parts 17 and 26 for the purpose of maintaining the tooth 25 of the latch 24 in engagement with the teeth of the rack bar 23 while per mitting the latch to recede and snap over the teeth of the rack bar as the latter is drawn back preparatory to a new. working .stroke as will hereinafter-appear.

' shaft 29. In the preferred embodiment of the feeding mechanism, the shaft 29 has fast thereon a cam 32 which coiiperates with the arm 33 of a lever designated genera-.

ally at D, the other arm 34 of said lever .be-

ing arcuate in shape and provided with a.

longitudinal slot 35. The lever is fulcrumed at 36 on the head frame B as shown in Fig. 4 and the arm 33 is maintained in working engagement with the cam 32 by means of a contractile spring 37 one extremity of which is attached to the arm 34 of the lever D and the other end attached to a fixed point on the head frame 13.

E designates a bell crank lever which is pivotally mounted at 38 on an extension 39 of the head frame B, one arm 40 of said lever having a jointed connection with the adjacent end of the reciprocatory rack bar 23. The other arm 41 of said lever has a jointed connection with a vertical plunger rod 42 and this plunger rod has pivotally connected thereto one extremity of a connecting rod or link 43 the other extremity of which is adjustably connected to the arm 34 of the lever D by means of a thumb nut 44. By loosening the thumb nut 44, the upper end of the rod or link 43 may be adjusted toward and away from the fulcrum point 36 of the operating lever D thereby increasing or diminishing the throw of the plunger rod 42 and correspondingly varying the throw of the rack bar 23 and the feeder head C. 1 This provides for regulating the thickness of the slices and under the proportionsof the parts as illustrated in the accompanying drawings the slices may vary from approximately one-eighth of an inch to one inch in thickness.

F. designates the slicing cutter having an eccentric shearing cutting edge 45 which works in conjunction with a straight-edged I ledger blade 46 fastened at '47 to the head frame A at the point where the material emerges from the trough. The opposite side ofthe blade is cut away to a'point beyond the axis of. movement of the blade as shown at 48 so that in one position of the cutter the end of the trough will be left entirely open, this position occurring just as a thrust or feeding movement is imparted to the feeder head C. A substantially cylindrical casing 49 houses in the blade F so as to prevent accident to a bystander or to the operator himself.

As the slices are formed by the cutter F, they pass beyond the cutter and upon a receiving trough 50 embodying a floor 51 substantially in the same plane with the floor 1 of the trough of the machine. The receiving trough is also provided with the upstanding sides or flanges 52 between which is a sliding abutment 53 preferably inclined as shown in Fig. 1 so that the tops of the slices will fall away from the cutter as the slices are successively pushed upon the receiving trough by the loaf or other object being sliced by the cutter. The loaf or other object is urged toward the front side of the trough by means of a leaf spring 54 which is best illustrated in Fig. 2, said spring being attached at one end as shown at 55 to one of the head frames and having a portion thereof extending longitudinally and obliquely of the trough so asto bear against one side of the loaf or object and keep the same constantly pressed against the front side of the trough.

After a loaf of bread sliced by the means hereinabove described, the feeder head C is stopped before coming in contact with the cutter E by reason of the length of the rack bar 23, the length thereof being such that when the feeder head G reaches the limit of its movement, the said rack bar will not be able to again reach and 'coeperate with the latch 24. Therefore,

there can be no further advance movement of the feeder head. The operator then grasps the handle 17 and latch releasing lever 26 and slides the feeder head back in position to receive a new loaf whereupon the operation of the machine is resumed. The receiving-trough 50 is preferably made detachable from the remainder of the mahas been completely chine by means of a bolt 56 to facilitate 7 storage and shipment.
